[vtkusers] java memory

Another problem. I wrote this small program and it leaks memory. Can
someone please explain why this program leaks memory. I call new once, and
then call delete on that object, yet I still leak memory, could someone
please explain what's going on? Is this a bug?
import vtk.*;
public class VTKMemoryLeak {
static {
System.loadLibrary("vtkCommonJava");
System.loadLibrary("vtkFilteringJava");
System.loadLibrary("vtkGenericFilteringJava");
System.loadLibrary("vtkGraphicsJava");
System.loadLibrary("vtkHybridJava");
System.loadLibrary("vtkImagingJava");
System.loadLibrary("vtkIOJava");
System.loadLibrary("vtkRenderingJava");
System.loadLibrary("vtkVolumeRenderingJava");
System.loadLibrary("vtkWidgetsJava");
System.loadLibrary("vtkgdcmJava");
}
public static void main(String[] args) {
for (int i=0; i<15; i++) {
vtkImageData image = new vtkImageData();
int[] extent = {0, 511, 0, 511, 0, 255};
double[] origin = {0, 0, 0};
double[] spacing = {1, 1, 3};
image.SetExtent(extent);
image.SetOrigin(origin);
image.SetSpacing(spacing);
image.SetScalarTypeToShort();
image.AllocateScalars();
image.GetPointData().GetScalars().FillComponent(0, 0);
image.Delete();
}
}
}
If I remove image.GetPointData().GetScalars().FillComponent(0, 0); and
instead add the following, I still leak memory
vtkPointData pointData = image.GetPointData();
vtkDataArray scalars = pointData.GetScalars();
scalars.FillComponent(0, 0);
However, if I add the following 2 lines I don't leak memory
scalars.Delete();
pointData.Delete();
Why do I have to call Delete on objects I don't new? This seems to have all
the makings of a memory leak on the VTK Java wrapper. Could someone please
tell me what's going on?
